Unable to run Corel Wordperfect 7 address book

I have installed WordPerfect Suite 7 on my XP machine. When I try to open the address book I receive this message: "Address book cannot be located. This is usually due to incorrect information in the registry." If I attempt to open the address book via Wordperfect document screen the messages says that I havn't loaded Microsoft Exchange (which I have) and to run a custom installtion of the address book. This hasn't worked either. Can anybody our there help me please?
